Fix crash in loading complex models. The issue was we were not freeing one local refrence in load_scene_node() (for the jassimp_node). We need to hold the local reference for the root node only.
Fix crash in loading complex models. The issue was we were not freeing
one local refrence in load_scene_node() (for the jassimp_node). We need
to hold the local reference for the root node only.

Due to this we exhaust the limit of 512 local references and there is a
crash. Fix is to release local references except for the root node.
